A deflection apparatus for a conveying system has a central body with a roller body which circulates around the central body, wherein the roller body has a multiplicity of rollers which are guided with play and roll in a roller track of the central body wherein the deflection apparatus forms an independent structural unit which can be assembled, dismantled and transported as a unit, and thus can be installed as an independent structural unit in order to deflect a conveying means in a conveying system. The deflection apparatus is preferably configured in a lightweight design, having rollers made from plastic and the central body made from plastic or aluminum.

1. A deflection apparatus for a conveying system, wherein the deflection apparatus comprises: a central body,a roller body circulating around the central body,wherein the roller body comprises a multiplicity of rollers, which are guided with play and roll in a roller track of the central body,wherein the deflection apparatus forms an independent structural unit, which can be assembled, disassembled and transported as a unit and can thus be installed as an independent structural unit in order to deflect a conveying means in a conveying system,wherein the rollers are guided in a roller belt and are distanced from one another, andwherein the roller belt is produced from a fabric or plastic-impregnated fabric. 2. The deflection apparatus for a conveying system as claimed in claim 1, wherein the deflection apparatus is realized in lightweight construction, with rollers made from plastic and the central body from plastic or aluminum. 3. The deflection apparatus for a conveying system as claimed in claim 1, wherein the central body is adjustable in its shape and a deflection angle of the deflection apparatus is thereby adjustable. 4. The deflection apparatus for a conveying system as claimed in claim 1, wherein the roller belt can be tensioned against the central body by means of a one-piece tensioning body, the tensioning body being fixed and the roller belt rolling with the rollers on the tensioning body. 5. The deflection apparatus for a conveying system as claimed in claim 4, wherein the tensioning body is mounted on the central body with a mounting, and the central body forms with the roller belt and the tensioning body an independent structural unit, which can be assembled, disassembled and transported as a unit. 6. The deflection apparatus for a conveying system as claimed in claim 1, wherein the roller belt is produced from a flexible flat material. 7. The deflection apparatus for a conveying system as claimed in claim 1, wherein the central body comprises a plurality of modular elements, which each form a sector corresponding to a partial deflection angle, and a plurality of such modular elements can be used to assemble central bodies for deflection apparatuses having different deflection angles. 8. The deflection apparatus for a conveying system as claimed in claim 7, wherein the central body further comprises at least one immobile element, acting as a roller track, which element extends over a plurality of the modular elements and, -over the whole of the deflection angle of the deflection apparatus. 9. The deflection apparatus for a conveying system as claimed in claim 1, wherein the roller belt comprises balls as rollers, and two of such roller belts are arranged such that they circulate around the central body. 10. The deflection apparatus for a conveying system as claimed in claim 1, wherein the roller belt runs with its two outer edges in a belt-guiding groove of the central body and is thereby guided and prevented from falling out. 11. The deflection apparatus for a conveying system as claimed in claim 1, wherein the roller body consists of a multiplicity of individual rollers, which are not chained together and which are arranged such that they roll round the central body and are distanced from one another by distancing bodies, the distancing bodies being mounted rotatably on the shafts of the rollers and preventing the rotating rollers from touching one another. 12. The deflection apparatus for a conveying system as claimed in claim 1, wherein the rollers have shapings for the transmission of axial forces to the central body, and the roller track comprises correspondingly shaped shapings. 13. The deflection apparatus for a conveying system as claimed in claim 11, wherein the rollers run with their distancing bodies or their axial ends in a retaining groove of the roller track, the retaining groove preventing the rollers from falling out of the roller track of the central body. 14. The deflection apparatus for a conveying system as claimed in claim 1, wherein the rollers are held against the central body by at least one circulating belt. 15. The deflection apparatus for a conveying system as claimed in claim 14, wherein the rollers comprise concave roller portions in which the at least one circulating belt runs, and the central body comprises corresponding guide projections, and the rollers are held in the axial direction by the engagement of the guide projections in the concave roller portions. 16. A deflection apparatus for a conveying system, wherein the deflection apparatus comprises: a central body,a roller body circulating around the central body,wherein the roller body comprises a multiplicity of rollers, which are guided with play and roll in a roller track of the central body,wherein the deflection apparatus forms an independent structural unit, which can be assembled, disassembled and transported as a unit and can thus be installed as an independent structural unit in order to deflect a conveying means in a conveying system,wherein the rollers are guided in a roller belt and are distanced from one Another, andwherein the rollers belt comprises recesses having bearing projections, and the rollers, with indentations, are inserted in the bearing projections and are thus loosely supported by the bearing projections. 17. A deflection apparatus for a conveying system, wherein the deflection apparatus comprises: a central body,a roller body circulating around the central body,wherein the roller body comprises a multiplicity of rollers, which are guided with play and roll in a roller track of the central body,wherein the deflection apparatus forms an independent structural unit, which can be assembled, disassembled and transported as a unit and can thus be installed as an independent structural unit in order to deflect a conveying means in a conveying system, andwherein arranged between the rollers and the conveyor means is a protective means, which rolls on the rollers and encloses the roller body on several sides. 18. The deflection apparatus for a conveying system as claimed in claim 17, wherein the protective means is formed by a succession of bar elements, which, following closely one upon the other and touching one another, roll on the rollers. 19. A deflection apparatus for a conveying system, wherein the deflection apparatus comprises: a central body,a roller body circulating around the central body,wherein the roller body comprises a multiplicity of rollers, which are guided with play and roll in a roller track of the central body,wherein the deflection apparatus forms an independent structural unit, which can be assembled, disassembled and transported as a unit and can thus be installed as an independent structural unit in order to deflect a conveying means in a conveying system,wherein the rollers have shapings for the transmission of axial forces to the central body, and the roller track comprises correspondingly shaped shapings, andwherein the roller are slightly cambered, i.e. barrel-shaped, and the roller track is correspondingly concave in shape. 20. A method for manufacturing a roller body for use in a deflection apparatus wherein the roller body circulates around a roller track of a central body of the deflection apparatus, having the following steps: forming a roller belt by cutting-out of recesses with bearing projections made from a strip-shaped flat material;inserting rollers, spaced from one another, into the recesses, the bearing projections coming to lie in indentations of the roller; andforming of a closed circle by overlapping or butt-joining and subsequent connecting of the two ends of the roller belt(4). 21. The method as claimed in claim 20, wherein ends of the roller belt which overlap upon formation of a closed circle overlap around the region of a roller or a plurality of rollers. 22. The method as claimed in claim 20, comprising the step: bonding or welding together, or stapling or sewing together, of the overlapping or butt-joined ends of the roller belt.7
